ADDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 494,618, dated April 4, 1893.

Application filed August 5.1390- Serial No. 361,037. (No model.) Patented in Germany July '7. 1889, No 50,885 in Austria- Hungary May 18, 1890, No. 22,697 and No. 44,377, and in England August 21,1890,N-13,538-

To all whom it may concern.-

Be it known that I, OSWALD BEHER, a subject of the German Emperor, residing at Gross Guhran, near Graase, Silesia, in the Empire of Germany, have invented a certain new and usefullmprovement in Adding-Machines, (for which I have obtained patents in Germany, dated July 7, 1889, No. 50,885; in Austria- Hungary, dated May 13, 1890, No. 22,697 and No. 44,37 7, and in Great Britain, dated August 21, 1890, No. 13,538,) of which the following is a specification, reference being made to the accompanying drawings, in which Figurel is aplan view of theimproved adding machine the top plate of the cover or case being removed to show the interior. Fig. 2 is a cross section thereof on line 2-2 Fig. 1, certain parts at the rear being however omitted for clearness of illustration. Fig. 3 is a cross section of the machine on line 33 Fig. 1,the crown wheel which bears the units and tens being removed. This figure shows parts omitted in Fig. 2. Figs. 4: and 5 are plan views of parts of the mechanism showing the same in different positions as hereinafter referred to.

In the improved machine a horizontal crown wheel provided on its circumference with a series of numbers from 0 to 99 inclusive is adapted to be revolved by a spring when released by the depression of any one of a series of keys numbered from 1 to 9 inclusive. The depression of any one of these keys causes a finger to be thrust forward to engage with pins, the equivalent of teeth on the crown wheel so that the said finger is carried along with the crown wheel on its revolution and arrests the movement of the latter by arriving against a stop pin moved into its path by the respective key so that the amount of revolution allowed to the crown wheel is equivalent to the value of the key. A hundred wheel is also provided and operated as hereinafter explained, and means are provided for setting both wheels simultaneously to zero.

The crown wheel a is fixed upon the vertical arbor b carrying also the toothed pinion c gearing on the teeth on the spring barrel (1 (see Figs. 1 and 2). This spring'barrel contains a coiled spring 01 and differs in no respect from the spring barrel of an ordinary clock. The spring may be wound up by a key applied to the square head 6 reached through a hole in the base platef of the machine. On the upper face, the crown wheel a is provided all round its circumference with a series of numbers from O to 99 inclusive equally spaced, (only a few of these being shownin the drawings.) On the under side, the wheel a is provided with a like number of projecting pins h equally spaced and equivalent to teeth. The crown wheel is prevented from revolving under the infiuence of the spring (Z in the barrel (1, by the book 9 which engages between the pins h. The spring 1' which encircles the post on which the hook g is pivoted and presses with one end on the back of the hook g tends to hold the hook g in engagement with the pins 72. The nine key leversj are pivoted on a cross bar It and are severally lifted at their front ends by springs Z so that their rear ends are usually depressed. Each lever j is provided at its rear end with a vertical pin m.

Extending under all the keys to be depressed by any one of them is the pivoted frame a carrying the arm 0. This arm 0 is connected by a rod 1) to one arm of the lever q, pivoted at r, as shown in dotted lines at that part of the lever g which is under the arm of the frame, Fig. l, and carrying pivoted to it, on its other arm, the rod 8 and the finger 15. The rod 8 is guided under the bridge 11, below the level of the ends of the pins 72 on the wheel a, and is directed against the plate -v which forms a downward extension of the hook 9 before referred to. The finger tpasses.

under the upper bridgew and over thebridgef a being free to move to and fro under said bridge w so far as the limits of the latter allow. The spring (l3 tends to throw the finger 2? against the left hand end or limit of its movement. The spring y tends to return the lever 61 to the position in which it is shown in the drawings after it has been moved as hereinafter described. The action of these parts is as follows: On depression of any one of the keys j, the pin m on that key is raised into the path of the finger 25;

the frame a is atthesame time depressed by the respective key 3, and rocks the lever g which throws backward the rod 3 and presses back the hook g, at the same time thrusting backward the finger if so that its end arrives between two adjacent pins h on the wheel a. The wheel a being released by pushing back the hook g flies round under influence of the spring 01 in the barrel d and carries with it 7 the finger 25, until the latter strikes against and'is stopped by the uplifted pin m on the key j which is depressed. further revolution of the wheel a which has therefore moved round through a distance proportional to the distance between the end of the bridge w and the raised pin 9%, which distance is proportional to the number indicated on the key depressed. Thus if key numbered 2 be depressed the distance through which the wheel a revolves before it (or rather the finger engaged with it) is stopped by the raised pin m on that key lever, is sufficient to replace the figure occupying the position of 00, in Fig. 1, by the figure greater by 2. This completed, the pressure is taken off the key, which rises allowing the parts to resume their first positions under influence of the springs 1,2', y, as shown in Fig. 1, the hook g holding the wheel a in its new position until depression of another key causes the same operations to be repeated. The springy holdsthelever q in theposition shown and through the rod 1) holds up the rocking frame 12. A window or open based funnel shaped depression 2 in the cover plate f of the case (Fig.3)will allow only the numbers on the wheel a and barrel d occupying the position of 00 in Fig. lto be visible through the casing. Thus the machine being set at O00 as hereinafter described the depression of the key marked 2 will cause 02 to appear at the window-if other keys, say those marked 5, 7, 9 be thereafter successively depressed the totals 7, 14, 23 will successively appear at the window.

On the wheel a'at any suitable position on the upper surface of the wheel is the pin a. An arm b radiating from a vertical arbor 0 extends across the wheel a in the path of the pin a. Alongside the wheel a is a vertically arranged wheel 61' carrying numbers 0, 1', 2, 3 and more if desired and the same number of projecting pins 6'.

Around the shaft g of the wheel (1' is coiled a cord h connected to the end of a rod t" which passes into the end of a cylinder j and terminates in a cross head or button 7c. The spring Z in the cylinder j tends to press the cross head of the rod 2" inward and so to re volve the wheel d in the direction of the arrow in Fig. 4.

On the arbor c is a projecting plate m slit longitudinally and having one part m at a lower level than the other part m The spring at, a coiled spring one end of which is fixed in any suitable way to the frame and the other end pressed against the back of any of the arms radiating from the arbor c or is fixed to the arbor c itself, Will tend to hold the arbor 0 so that the arm I) rests against This stops the some fixed stop for instance conveniently the arbor b of the main crown wheel a. In this position the higher part m of the plate m lies in the path of the pins 2 and the latter, one of them rests thereon under the pressure of the spring Z in the cylinder j. As the wheel a revolves the pin a will arrive against and move the arm I) until when the wheel a marks 99 the parts will be in the position shown in Fig. 4. During this movement the higher part m of the plate m will have given place to the lower part m as a support for the pin e and the Wheel 61 will have rotated slightly. When the pin a moves from under the end of the arm I) the latter resumes the position shown in Fig. 1 and the pin 6 which was resting on the part m will slide off that part under the part m and the wheel d will. revolve sufficiently to bring the next hundred before the window, the next pin 6' arriving on the higher part m of the plate m. V

For resetting to zero the following mechanism is added, 0 is a thrust rod ending outside the casing in a button 0 and adapted when pushed in to perform the several disengagements necessary for resetting the apparatus to zero. On the wheel a is a pin 19 and on thepivoted bar q is a nose 0* adapted to be brought into the path of the pin p when the bar g, which engages in a notch s on the rod 0, is pushed inward by said rod. The inner end of the rod 0' is adapted to disengage the hook 9 (Fig. 5) so that the wheel ais freed and revolves until the pin p is stopped by the nose 1" which will bring the zero of wheel a under the window. The rod 0' carries an arm t entering into a slit to in the cylinder j and also an arm 1) adapted to strike against and deflect the arm w on the arbor o. 7

In the wheel d is a spring 00' (see Fig. 3) the tension of which is contrary to that of the spring Z but weaker so that the latter spring when in action overcomes the spring so. When the rod 0 is pushed in, the arm 25' compresses the spring Z' and relieves the wheel d of the tension of this spring so that the wheel d can now be revolved back to its zero position by the spring so. At the same time the arm 1 so far moves the arm to that the plate m is brought entirely out of the paths of the pins e and the wheel (1' is so left free to assume the position given to it by the spring as. The spring y operates'the return of the rod 0'.

I do not claim broadly the construction by which the movement of the number wheel is limited at each stroke by a pin the position of which corresponds to the position at which the wheel must be arrested to indicate or add the number corresponding to that indicated on the key depressed with which the respective pin is in connection, but

I claim- 1. In an adding machine-the combination of a rotary crown wheel having pins thereon,

a series of key levers adapted to be vibrated by hand, a loosely vibrating finger adapted to be thrust between the pins of said crown wheel on depression of any key lever, and a pin on each key lever adapted on depression of the respective lever to be moved into the path of said vibrating finger to limit the movement of said finger whereby the rotation of said crown Wheel is limited to an amount pro- IO portional to the indication on the respective kev.

2. The combination of a rotary crown wheel having pins thereon, a series of key levers adapted to be vibrated by hand, a loosely vibrating finger adapted to be thrust between the pins of said crown wheel on depression of any key lever, a pin on each key lever moved on depression of the key lever into the path of said vibrating finger to limit the movement of said finger, a pawl g for locking the crown wheel, adapted to be thrown out of engagement therewith on depression of any key lever, and a spring barrel or equivalent motor d d for rotating said crown wheel when re- 2 5 leased.

. The combination of the crown wheel a having the series of pins h, the key levers 7', pins on on said levers, the lever frame at with arm 0, rod 9, lever q, vibrating finger t, rod 8, hook g and motor (1 (1 adapted to co-operate substantially as set forth.

4. The combination of the rotary numbered wheel a, the pin a on said wheel, the arbor c, the radial arm I) and divided plate m with higher stage m and lower stage m the 1'0- tary wheel d having pins 6 and numbers thereon, and a motor for said wheel (1' substantially as and for the purpose set forth.

5. The combination of the wheel d, having pins e thereon, arbor g, cord h rod 71 and spring Z, of the rod 0 having the arm t for compression of said spring Z and the arm a; the arbor c with arm to and divided plate m, adapted to be rocked by said arm a; and a spring 00 adapted to reset the wheel d to zero as and for the purpose herein described.

In testimony whereof I have signed this specification in presence of two witnesses.
